Abstract: A directional garlic seed throwing mechanism includes a base, a rotating device, a vision sensor, a seed throwing guide plate, a seed guide pipe and a plurality of bulbil adjusting devices. The rotating device includes a rotating motor detachably connected to the base and a turntable connected to an output end of the rotating motor. The seed throwing guide plate is arranged on the turntable to enable garlic seeds of seed containing bowls to fall into the seed guide pipe. The seed guide pipe has an upper port right below the bulbil adjusting devices and arranged on the base. An even number of the bulbil adjusting devices are fixed on the turntable uniformly and symmetrically and include the seed containing bowls and bulbil direction control devices for driving the bowls to rotate 180 degrees.

Abstract: A motor-driven single-seed-ejection sowing device includes a housing, a seed metering roller, a seed brush, a seed metering mechanism and a power mechanism. The housing includes a power compartment and a seed compartment. The surface of the seed metering roller is provided with seed grooves having spaces for accommodating a single seed. The seed metering mechanism includes a spring, a striking tube, a piston and the piston tube. The piston and the piston tube are arranged for axial movement inside the striking tube. The power mechanism includes a control unit and a drive unit. The control unit includes the motor, the drive panel, the Hall sensor and the magnet. The magnet is set on the striking tube. The Hall sensor and the drive panel are connected to the motor, and the motor drives the seed metering roller and seed metering mechanism by the drive unit.
